Step 1 of 1

Carbon is belongs to 4A group. Its atomic number is 6. So, the
carbon has 6 electrons. Its electronic configuration is
. In the carbon atom, the outer most orbitals (valence orbitals)
are
. These are second-row orbitals. Therefore, the valence electrons
present in outer most orbitals ()
are 4.

The electronic configurations for 4A group elements are as shown
below:

From the above table, the third-row of silicon (Si) has the same
number of valence electrons
as carbon
.
